Chemical composition and biological activities of whole and dehulled hemp (Cann...

Alonso-Esteban, José Ignacio; Pinela, José; Ćirić, Ana; Calhelha, Ricardo C.; Soković, Marina; Ferreira, Isabel C.F.R.; Barros, Lillian

This study aimed to determine a complete chemical composition of eight different varieties of whole hemp seeds and eight samples of commercial dehulled hemp seeds. We also evaluated the phenolic profiles and antioxidant, cytotoxic, and antimicrobial properties of hydromethanolic seed extracts. Whole hemp seeds contain much more fibre than dehulled hemp seeds, which contain more fat and protein. Sucrose and raff...

Pires Junior, Eleomar de O.; Pereira, Eliana; Carocho, Márcio; Pereira, Carla; Dias, Maria Inês; Calhelha, Ricardo C.; Ćirić, Ana; Soković, Marina

Flowers of the genus Impatiens are classified as edible; however, their inclusion in the human diet is not yet a common practice. Its attractive colours have stirred great interest by the food industry. In this sense, rose (BP) and orange (BO) I. balsamina flowers were nutritionally studied, followed by an in-depth chemical study profile. The non-anthocyanin and anthocyanin profiles of extracts of both flower v...

Tomato plant biomass: from agricultural by- products to bioactive extracts with...

Pinela, José; Añibarro-Ortega, Mikel; Ćirić, Ana; Rocha, Filomena; Barata, Ana Maria; Soković, Marina; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.

Tomatoes are highly consumed worldwide and their annual production generates a significant amount of plant by-products, especially aerial biomass. Although tomatoes are well-known for their nutritional composition and health-promoting effects [1], little information is available in the literature on the plant remains of this crop. Therefore, considering the substantial availability of this natural resource and ...

Añibarro-Ortega, Mikel; Pinela, José; Ćirić, Ana; Rocha, Filomena; Barata, Ana Maria; Soković, Marina; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.

Table tomato (Solanum lycopersicum L.) is highly consumed worldwide and its annual production generates a considerable amount of plant by-products [1]. Although tomatoes are well-known for their composition in nutrients and bioactive compounds [2,3], little information is available in literature regarding tomato leaves, probably because these by-products have no commercial value. Therefore, considering the enor...
